I have five tractors that are identical in appearance. I conducted a little free ranging experiment today and I firmly believe my adult rooster couldn't figure out which tractor was his to lead his ladies back to their roost. In the end it took a combination of four tomcats, me, my daughter, a hunting dog, and four foot long bamboo 'guiding rods' to get them back where they belonged. Are chickens noted for their ability to find their way back to the coop? Because I have zero faith in this guy.
